Frequently Asked Questions: OE 18039690-00
What if the number on my old disc is different to this one?
If the number on your old disc reads differently from 18039690-00, do not fit this one on the strength of the model name alone. This disc is made for the Song Ultra EV and Tai 3, so the model name will not tell you enough. Use the quote route on this page and give the number from your old disc. That way the part matched to you is based on what is actually fitted to your car, not on the badge on the back.
Do I need a garage to fit this front brake disc?
Brake work needs to be done correctly since it affects how the car stops, so if you are not confident handling this yourself it is worth having someone qualified do the job. Before you order, check the old disc that is currently on the car, and match its OE number against 18039690-00 or the alternative reference UREA-3501111S. That comparison tells you whether this is the right disc, whatever set of hands ends up fitting it.
How does a part this size get delivered?
This is a single boxed item. The packaging details are shown on this page. Delivery takes 8 to 28 days from your order to your door. Do not take the old disc off the car until you have checked the number stamped on it against 18039690-00. That single check, done before delivery, is what tells you the part on its way is the right one for your Song Ultra EV or Tai 3.
What is the front brake disc made of?
It is metal, new and made by BYD, not a reconditioned or pattern part. A metal disc gives a firm, consistent pedal feel and is the standard choice for this position, fitted underbody at the front of the car. Before you order, take your registration document and check the model and the model year shown on it, since brake discs are matched closely to those details. Getting this right first time means the disc bolts straight on without any comeback to the parts counter later.
Where does this front brake disc fit on the car?
This is listed as a front disc, fitted at the underbody position on the car, not a rear one, so it goes on the front axle rather than the back. It carries OE number 18039690-00, also listed as UREA-3501111S, so check that number against the disc you are removing before ordering, since matching the OE number is the surest way to know it is the right side and position for your BYD. If the number does not line up, hold off and check further before fitting.
